JOHN E. DOOLY, OF ST. LOUIS, MISSOURI.

GAS-BURNER ATTACHMENT FOR STOVES.

SPESIFICATION forming part of Letters Patent No. 338,143, dated March 16, 1886.

Application filed February 16,1884. Renewed June 1, 1885. Serial No. 167,284. (No model.)

To all whom it may concern:

Be it known that I, JOHN E. DOOLY, of the city ofSt. Louis, in the Stateof Missouri, have invented a certain new and useful Improvement in Gas-Burner Attachments for Stoves, Ranges, &c., of which the foilowing is a full, clear, and exact description, reference being bad to the accompanying drawings, forming part of this specification, and in which Figure l is a perspective view of the attachment, and Fig. 2 is a vertical section of same and part of a stove or range.

My invention relates to those gas-burners or apparatuses for burning gas which can be applied to an ordinary stove or range, as hereinafter more fully described.

My invention consists in features of novelty pointed out in the claims.

Referring to the drawings, A represents part of an ordinary stove or range.

B represents a ring adapted to fit in one of the pot-holes of the stove or range, as shown in Fig. 2. To this ring is secured, by means of arms D,a disk or circular plate, 0, with an opening or perforation, I, in its center for the passage of air, and an opening, 0, at one side for a supply-pipe.

Resting upon or secured to the disk within the skeleton frame thus formed is a box or cap, J, forming with the circular plate an annular combustioircliamber, L. The box rests upon the disk between outer and inner flanges, N.

0 represents the supply-pipe connected to the opening 0 in the bottom of the disk and communicating with the chamber L. The pipe extends out through one of the doors or other opening in the Walls of the stove or range, and its outer end is provided with a suitable nozzle and valve, P, to which a hose or tube may be connected; The gas entering the chamber L passes out through perforations Lin the inwardly and downwardly inclined top L, where it ignites and burns. The perforations are made so as to point toward the center of the burner, so that the jets of gas passing through them project toward a common center, thereby forming or producing a draft or current of air upward through the burner, as shown by dotted arrow, Fig. 2, to assist the combustion. The combustion is also assisted by the gas being superheated in the chamber L. The pro ducts of combustion pass between the top of the box and the ring B, and are carried off through the chimney or flue of the stove or range. V

I do not claim, broadly, a gas-burner suspended by means of arms from a ring located within the pot-hole of a stove, as I am aware that this construction is old.

I claim as my invention-- 1. A gas-burner attachment for stoves, consisting of a skeleton frame having a ring, B, arms D, and a bottom plate, 0, formed with a central opening, I, side opening, 0, and concentric flanges N N, a supply-pipe connected with the side opening, and an annular boX, J, having perforations L, and resting on the plate between the flanges within the frame, and forming with the plate an annular chamber, L, substantially as set forth.

2. A gas-burner attachment for stoves, consisting of a skeleton frame having a ring, B, arms D, and a bottom plate, 0, formed with a central opening, I, side opening, 0, and concentric flanges N N, a supply-pipe connected With the side opening, and an annular box, J, having inwardly and downwardly inclined top L, formed with perforations L, and resting on the plate seated against the flanges within the frame, and forming with the plate an annular chamber, L, substantially as set forth.
